Zeehan Gravity Survey, 2006 (P200671), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Zeehan Gravity Survey, 2006 (P200671) contains a total of 3260 point data values acquired at a spacing between 10 and 100 metres. The data is located in TAS and were acquired in 2006, under project No. 200671 for Zeehan Zinc Ltd.

重力数据用于表征地球表层下方岩石密度变化引发的微小重力场变化。所采集的数据将通过标准处理流程进行处理，以确保记录的响应仅源于地下岩石的影响。经处理得到的数据集可通过解译揭示地下地质构造。由GA地球物理学家对处理后的数据进行质量核查，以确保GA发布的最终数据符合使用要求。本次2006年齐恩重力测量项目（P200671）共包含3260组测点数据，测点间距介于10米至100米之间。该数据集采集于塔斯马尼亚州（TAS），于2006年由齐恩锌业有限公司（Zeehan Zinc Ltd）依托编号为200671的项目完成采集。
